What Is the Cause of Toothaches and Why It Gets Worse at Night?


Toothache is not an ordinary pain. Toothaches are one of the most unpleasant and painful experiences. Many people don’t know why toothache hurts so much. Apart from the pain, you might also have to deal with teeth sensitivity and difficulty with drinking and eating. Toothache can impact your brain and you cannot think straight while facing this pain. 

Most toothaches are caused by inflammation in the inside portion of the tooth. The tooth contains thousands of nerves that are extremely sensitive to pain. This can cause throbbing pain that makes the toothaches unbearable. 

What Are the Primary Causes of Toothaches?

Toothaches can be caused due to issues with your gums and teeth. However, other physical pain can also cause toothaches. Here are some common causes of toothaches:

  • Tooth decay: Different types of bacteria causes tooth decay. The nerves in your teeth will be damaged and you will experience pain. 
  • Mouth injury: Unexpected minor or major mouth and jaw injuries can cause toothaches. 
  • Infected tooth: This is known as a dental abscess. This condition is also considered as a pocket of pus in the tooth. 
  • Gum disease: Periodontal and gingivitis diseases can cause extreme toothaches. 

Even though there are other causes of toothaches, these are the primary. Despite the cause, toothaches won’t let you sleep or eat properly. If you’re experiencing toothaches, make sure you contact Dublin Dental Care as soon as possible. 

Why Toothache Do Gets Worse at Night?

As per Healthline, inflammation or infection in the tooth is the primary causes of toothaches. Toothaches enhance the sensitivity of your dental nerve to an extreme degree. This is the primary reason why toothaches become so severe at night. As the nerve stimulation becomes activated, it will prevent you from sleeping peacefully. Sometimes the pain and anxiety disrupt your sleeping pattern even more. In some cases, the foods you eat can also trigger toothaches. Foods or drinks that are very cold, hot, acidic, sugary, or starchy will worsen the toothaches. As you don’t feel any distraction at night, the pain from toothaches feels worse and becomes more obvious. Sometimes, the toothaches will worsen when you sleep, due to the blood circulation in your head, which will put extra pressure on the sensitive areas of the mouth. 

How Can You Remove Toothaches at Night?

While experiencing toothaches, it’s suggested to visit a doctor instead of treating the pain on your own. The doctors will provide you with a permanent solution. However, if the toothache pain is unbearable and you want to get rid of it temporarily, here are some effective ways to reduce the pain:

  • Use over-the-counter medication: Different types of medications such as aspirin, acetaminophen, and ibuprofen can help you get temporal relief from toothaches. You can also use numbing gels or pastes. 
  • Make sure your head is elevated: If you pop your head higher than your body, you can prevent blood circulation in your head. If blood starts circulating in your head, it might trigger tooth pain and prevent you from sleeping. 
  • Don’t eat hot or cold foods before bedtime: This is another great temporal solution to get relief from toothaches. Hot or cold foods can aggravate any cavities. These foods will ultimately make toothaches unbearable. 


These are the causes of toothaches and why the situation becomes worse at night. Toothaches are undoubtedly an extremely painful experience. Even though toothaches can go away, you should not wait for days to end toothaches. Instead, you need to consult with a professional dentist.
